GAS-BURNER;

Specification of Letters Patent.

Patented July 30, 1912.

Application filed July 10, 1911. Serial No. 637,824.

To all whom it may concern:

Be it known that I, CHRIST G. FARnz, a citizen of the United States,residing at Coney Island, in the county of Kings and State of New York,have invented new and useful Improvements in GasrBurners, of which thefollowing is a specification.

This invention is in the nature of a gas burner and the object of theinvention is to provide improved means on a gas burner in the nature ofa supplementary valve and controller, and automatic, operating means,whereby when the ordinary cut off valve is turned off, even if it isaccidentally turned too far, or turned back to open position, thesupplementary valve will be instantly closed and all flow of gas throughthe burner prevented, thus preventing the accidental asphyxiation of theoccupants of the room or house, in which the burner is located.

In carrying out my invention for the purv pose set forth my improvedconstruction will also instantly cut off the flow of gas through theburner in the event of a temporary cutting off of the pressure in themains, or back pressure therein, whereby the flame is extinguished, thuspreventing the accidental flow of gas which sometimes oc curs under suchcircumstances, especially where a gas jet has been left lighted allnight, and the consequent accidental death of the occupants of the roomor house.

With these, and such other objects as may hereinafter appear, in View,the invention consists in the improved construction, arrangement andcombination of the parts of my apparatus which will be hereinafter fullydescribed and afterwards specifically claimed.

In order that a clear understanding may be had of the construction andoperation of my invention, I will now proceed to describe the same inconnection with the accompanying drawing which illustrates a preferredembodiment and in which 1 Figure 1 represents a longitudinal, sectionalview on a plane cutting centrally through the burner pipe and the casingof the supplementary valve, the float being in elevation. Fig. 2represents a longitudinal, sectional view on a plane cutting centrallythrough the burner pipe, controller and casing, and supplementarywalvecasing at a right angle to the plane of Fig. 1 Fig. 3

represents a sectional view on a plane cut-.

ting transversely through the burner pipe and controllerand casing, 'asindicated by the broken line 3'-3 of Fig. 1.

Like reference characters mark the same parts wherever they occur in anyof the figures of the drawing.

Referring specifically to the drawing, 5 indicates a burner pipe of anyordinary construction with the exceptions hereinafter noted; having oneend threaded for attachment to the ordinary gas-supply pipe, the latterbeing provided with the usual cook, or cut-oil valve. At the oppositeend of the burner pipe 5 is attached in any usual manner. at 6, anyapproved or usual form of tip.

Near its inlet end the burner, tube 5 is provided with oppositelydisposed branches or nozzles 7 and 8 upon the former of which isthreaded a sleeve or casing 9 closed at its outer end by any suitablemeans, in this instance a cap 12 being shown.

In the nozzle 8 is threaded a plug 10 which is provided with a centralbore closed at the outer end 11 of the plug, said hollow plug serving asa casing for a rotary valve plug 19 of a supplementary valve which plugextends transversely through the pipe 5 and into the sleeve 9, beingreduced in diameter at 20 within said sleeve.

Theplug 19 is provided, with two oppositely located ports, as at 18, 13,extending longitudinally in the plug from the pipe 5 and at theiropposite ends turned inwardly, at right angles, as at 13*,- 13 andleading into the central bore.

There is provided in the pipe 5 a partition 22 which closes the pipe atthis point and leaves no other openingthan the lower port 13 for theflow of gas from the supply pipe.

The rotary valve plug 19 is provided with a diametrically located port20 extending entirely through it in the same transverse plane as thebranches 13 of the ports 13,

and a spring 21, coiled around the reduced portion 20 of the rotaryvalveplug 19 in the sleeve 9, is secured at one end to the sleeve 9 andat theother end to the valve plug 19 and is so aranged that it will hold theplug 19 normally in a position in which the ports 13 13 are out ofregister with the transverse port 20 of the plug and the flow of gasthrough saidports is cut off.

The pipe 5 is provided with an annular, inwardly extending ledge orflange 14 upon which normally rests a float valve 30 connected by acord, chain, or other flexible connection 29, with an arm 19*-projecting radially from the rotary valve plug 19 within the pipe 5,said flexible connection being of a suitable length to be stretched whenthe plug 19 is in 1ts normal position, in which position the ports inthe valve casing and valve plug are out of register and the valveclosed, as before stated, the float valve 30 being held down on theledge 14, which thus forms a seat for said float valve, upon which it isdrawn by means of the connection 29, and spring 21 which turns the plug19 and its arm 19 On one side of the pipe 5 near the tip end thereof andparallel with the casings of the valve plug 19 is secured by a threadedproj ection 15 and thread 17, a transverse casing 18 closed by a cap 25,in which casing is rotarily mounted a controller 23 from one side 'ofwhich projects a radial arm 27 projecting through a vertical slot 16into the pipe 5 and terminating substantially at the center of saidpipe, said arm being connected by a cord, chain, or other flexibleconnection 28 with the top of the float valve 30. A handle or button 24is mounted on a stem 26 of the controller 28, by means of which thecontroller may be turned, and the length of the connection 28 is suchthat when the controller is turned in a direction to stretch saidconnection, the float valve 30 is raised ofl its seat 14 and the valveplug 19 turned to bring the ports 13, 13 into register with the port 20thus opening a passage for the gas through said ports and around thesides of the float valve.

The controller plug is reduced in diam-- eter, as at 23 and about thisreduced portion is coiled a spring 31 secured at one end to the plug andat the other end to the casing, said spring being only strong enough tomaintain the plug normally in position to permit the float valve 30 torest on its seat 14, leaving the flexible connection 28 barely stretchedand free to slacken up when the float valve raises by floating, off itsseat at 14.

The spring 21 on the valve plug 19 is strong enough to normally holdsaid plug turned to keep the port 20 out of register with the ports 1318 but is not so strong as to draw the float valve 30 down upon its seat14 when the ordinary flow of gas is passing through the pipe, so that,as soon as the valve plug 19 is turned to open position, and the valve30 raised ofl its seat 14, by turning the controller, and the ordinarypressure of gas is passing through the pipe 5 to the tip, the floatvalve is held raised olt its seat by the gas, holding the plug 19 in theposition in which the port 20 is alined with branch ports 13, 13. Inthis position the proper amount of gas will pass out to be fullyconsumed.

Should the ordinary cut-oil valve be turned to closed position, thecutting 011' of the gas from pipe 5 will permit the float valve 80 todrop upon its seat 14 and the slacking of its flexible connection withthe valve plug 19 will permit the spring 21 to turn that plug to itsclosed position, thus further preventing the passage of gas. Should theordinary cut-off valve be turned beyond the closed position, oraccidentally be, turned back to open position, the result with the floatvalve 80 and valve plug 19 will be the same. The gas will be cut ofl theinstant the closed position of the cut-off valve is reached, no matterwhat is done with the cut-off valve afterwards. While the plug 19remains in its closed position, the restored gas pressure has no effectupon it and no gas can possibly pass to the tip and escape, until thecontroller is turned, the float valve raised ofl' its seat, and thevalve plug 19 turned to open position.

Having thus fully described my invention what I claim as new is:
